What is the best aftermarket exhaust for a Nissan 370Z?

I just bought a Nissan 370Z and I want to improve its exhaust sound and performance. I am looking into getting an aftermarket exhaust, but there are so many options out there. Which one would you recommend?

I would highly recommend the Invidia Gemini cat-back exhaust. It has a deep, throaty growl and adds a noticeable performance boost to your 370Z. I have one on my Z and I couldn't be happier with it.

Personally, I've had great experience with the HKS Hi-Power exhaust. It has a nice balance of sound and performance, and it's also one of the more affordable options out there.
